Abstract
A transparent glazing panel comprising at least one sheet of coated glazing material bears on a first sheet face 3 a first light transmitting coating 13 at least 400 nm in thickness which comprises doped tin oxide and/or doped indium oxide and reduces the emissivity of that sheet face in respect of infra-red radiation having wavelengths in excess of 3 .mu.m. On a second sheet face 1, the panel bears a second light transmitting metal oxide coating 21 which comprises at least 30% tin and at least 30% titanium calculated as weight percent of the respective dioxide in that second coating. The second coating 21 increases the reflectivity of that sheet face in respect of normally incident visible light to at least 20%, while the light absorbing properties of that second coating are such that it has a computed internal transmission factor in respect of visible light of at least 60%.
